@@ -6,6 +6,7 @@ A while ago I bought a UPS (Uninterruptible power supply) from Amazon Basics.
 I tried multiple drivers for it, but they all had their problems:
 - **NUT** tended to mess up the USB connection after some days to a point where you had to **unplug and re-plug the USB cable** of the UPS
 - UPower had a stable connection, battery percentage was updated in real-time, but the **charging state was frozen**, displaying `fully-charged` when UPS was at 5% charge or displaying `charging` when UPS was already at 100%
+- ..and many more that didn't work at all.
 
 So I tried writing dirty fixes for both of those drivers, which would reset the USB connection when detecting such problem. But it wasn't as stable as I had hoped.
